MACHINE FOR CUTTING LEATHER INTO HOLLOW-WARE FORMS.

Specication of Letters Patent No. 7,424, dated June 11, 1850.

To all 'whom/@'15 may concern: Y

Be it known that we, FRANCOIS DURAND and ONESIPHORE PECQUEUR, of Paris,in the Republic of France, have invented fa certain new and usefulMachine for Manufacturing Articles of Leather Without Seam or Cement,and that the following is a full, clear, and exact description of theprinciple or character which distinguishes it from all other thingsbefore known and ofthe usual Inanner of making, modifying, and using thesame, reference being had to the accompanying drawing, which forms apart thereof, in whichi Figure l is an elevation of the machine, Fig. 2is a plan.

The same letters refer to like parts in both figures.

The machine which is the subject of the present description and claim isfor the purpose of making shoes of all kinds, boot legs, cartridgeboxes, hats, caps, hose, fire buckets, gloves, &c. and consists of anupper frame A supported by six posts or legs B and braces C connectingthem. That part of the machine which holds the leather, and advances itto the knife to be cut consists of two rollersD D the lower D havinglongitudinal grooves cut in it parallel with the axle and supported in aswing H which is` joined to A so thatit can be raised or 10W- ered atpleasure; and the upper roller being grooved around its circumferenceasclearly shown in Figs. l and 2. This roller is sus-` pended in a frameF which is connected by.

its center with, and is borne by a lever E jointed by one end to theframe A and secured by the other to a catch E2. `These rollers, when inplace, are geared together and are connected with the driving shaft J bymeans of a train of gearing consisting of an endless screw or worm wheelK on said shaft J that works into a gear wheel L on a upright shaft` onthe upper end ofwhich,

above frame A there is a bevel wheel O gearing into another O on the endof the lower roller D above named.

On the upper end of the shaft J there is a plate of metal P which formsan adjustable eccentric; upon this plate are two guides l and 2 alongwhich the crank pin 3 is made to slide radially by means of a screw 6which Vturns in a bearing 9 affixed to the plate, and working into a nuton the slide 3 of the crank pin 3 to move it out or in, to or from thecenter or shaft J; two small ratchet wheels `of metal 7 may be aliixedto the end of the screw, which, as the plate P revolves,by being actedon by a dog 8 that is moved up and down by the circular n grooved ringlO strikes the ratchet which causes it to revolve (one of these causesthe screw to turn one way, the other in a contrary direction, bystriking the ratchet either above or below the axis).

The crankpin 3 is connected with the arm R to which the knife isattached by an adjustable connecting rod Q. The arm R is connected withthe frame A by a fulcrum S on which it slides back and forth by means ofa collarU so as toV give the knife a straight motion parallel with, andin front lof the rollers, which motion is insured by the connecting linkV as in ordinary parallel motions. A guide W is affixed to the frame Ato steady the knife in its vibration. "The dogs 8 can be thrown out orinto contact with the ratchet wheel 7 to curtail or extend thevibrations ofthe knife, so as to form a margin of any shape that may berequired, by lowering or raising the ring l0. This is done by itsconnection with a cam 12 by means of the shaft ll and its connections.

W'hen the leather is presented to this machine the rollers D D areadjusted to the knife Z so as to have the cut made in the center of thethickness, the parts are then put in motion by the driving pulley I orthe shaft J which communicates with this motive power, and the rollersare made to revolve and draw in the leather, While the knife is put intomotion and splits it to the breadth permitted by the adjustable crank.instead of the adjustable crank a pattern can be introduced to regulatethe vibrating of the knife. i

Having thus fully described our improved machine, and its Inode ofoperation, What and the other circumferentially serve lirmly We claimtherein as new, and desire to secure to hold the leather in anyposition.

by Letters Patent is- The combination of the vibrating knife 5 with thefluted rollers, constructed and operating substantially Vin the mannerand for Witnesses: the purpose above fully set forth, one of L. RUOHET,Which rollers being uted longitudinally JOHN BARTLY.
